Testing & Commissioning
Testing & commissioning is done once all civil & MEP system installation is completed, inspected and approved.
Before starting the testing and commissioning activities a comprehensive testing & commissioning plan is prepared and approval is taken from client/consultant.
It is discussed and mutually agreed whether the testing and commissioning can be done on temporary power supply or the permanent power is mandatory.
All calculations related to temporary power requirements are done and generators with voltage stabilizers are provided so that equipment are not damaged due to fluctuations in the power supply.
Before starting the Testing & Commissioning, method statements are prepared by all subcontractors, suppliers, TAB agency and any involved third parties etc.
These method statements including ITP, Checklists and risk assessments are submitted and approval is taken before starting the individual system testing and commissioning activity.
All pre-commissioning and commissioning activities are witnessed as per approved ITP, by main contractor / consultant / client / end user representatives.
Execution of testing & commissioning is done in the following sequence:
- Arrangement of temporary / permanent power in line with the load demand of the project equipment’s.
- Coordinating with suppliers and calling them for standalone testing / pre-commissioning as per approved commissioning plan.
- Approval of pre-commissioning for each system before going for final testing & commissioning stage i.e. closing of comments.
- Final testing, Commissioning & integration by suppliers / third parties including closing of all comments.
End User Training’s:
Once the testing and commissioning is completed and approved now the system is ready for handover to client but before final handing over end user trainings are conducted for facility management or maintenance team of client/ end users.
Trainings are conducted as per agreed plan with client & specialist suppliers.
As required training are conducted in two stages:
- Office presentation for over view of the system
- Site demonstration by the trainers including the answers to any questions raised.
Hand Over of the Project
Once all the project systems are tested, commissioned, approved and integrated with other systems i.e. fire alarm, lighting control system and building management systems, finally these are handed over to the client officially and Provisional Acceptance Certificate / TOC is issued from client.
From the date of project handover defect liability period starts, during which installer/supplier is responsible for any complaint handling and maintenance etc.
At this stage following steps are ensured:
- Handing over of operation and maintenance manuals, already approved.
- Handing over of warrantees/guarantees, already approved.
- Handing over of spare parts, already approved & procured.
- Submission of close out report with recommendations for facility management FM team
At the same time project team hands over the systems to its FM department which then takes control of any routine maintenance requirements of the project during the Defect Liability Period.
During the defect liability period dedicated resources are available 24 hours for attending any complaints and corrective & preventive maintenance requirements.
A copy of O&M Manuals is also handed over to maintenance team for ready reference of the testing and commissioning records, warrantees and other troubleshooting guide lines.
Once Defect Liability Period is completed the project is finally handed over to the client as per the contract, with final report mentioning critical areas for maintenance and recommendations for the client for smooth operation of the MEP systems in future.
